TECHNICAL FIELD

The present invention relates to a henhouse, and more particularly, to apremixed ventilated henhouse.

BACKGROUND

At present, a henhouse is mostly ventilated in a manner of negativepressure ventilation. One gable is provided with a fan thereon, twosidewalls are provided with wet curtains thereon, and fan operates tocause a negative pressure inside the henhouse, so that wind entersthrough the wet curtains. However, the wind entering the henhouse isrelatively strong, especially in seasons of autumn and winter, with alarge volume of urgent and cold air. The cold air partially sinksquickly, which is unable to be evenly mixed with hot air in thehenhouse, rendering fowls uncomfortable. Moreover, a majority ofhenhouses are provided with a built-in wet curtain, which is embedded inthe sidewall of the henhouse. An outer surface of the wet curtain ismerely provided with a simple dust screen, so when an outdoortemperature is excessively low, especially in cold winter in the north,the outdoor cold air is apt to enter the henhouse through the wetcurtain, resulting in problems such as that the henhouse is hard to bewarmed up. Patent Application No. 201320159133.4 and Patent PublicationNo. 203136769U disclose an aerosol-type ventilated henhouse, in which avent-pipe ventilated with external environment is provided on the gableand the sidewall of the henhouse, which is able to achieve an effect ofevenly mixing the air. But, foul gases sink and accumulate below withinthe henhouse, so there are still problems such as that foul gases arehard to be exhausted, and ammonia excesses the standard. In addition,temperature and humidity of outside air are unable to be adjusted andcontrolled according to an actual situation of the henhouse, whichresults in a poor overall ventilation effect on the henhouse, andaffects health of the fowls.

The outdoor fresh airenters the premixing chamber in the upper portion of the henhouse bymeans of the air deflector through the wet curtain, and the air in thepremixing chamber is heated up or cooled down through the warm waterpipe or the atomization pipeline according to the requirements. Thepressure chamber discharges the mixed air into the inner chamber, and ata same time, the foul air inside the henhouse, especially the foul gasthat sinks in the lower portion of the henhouse as mobilized by the fanof the sidewall and the fan of the vent pipe, passes through the airoutlet slot of the inner wall or the through hole of the floor to bedischarged, while the fresh air sinks as a whole, so as to implementoverall air renewal inside the henhouse. In addition, the wet curtain onthe sidewall of the present invention is able to meet a demand forcooling down the henhouse when the outdoor temperature is relativelyhigh, such as in summer. The thermal insulation curtain is alsoprovided, which plays a role in keeping the henhouse warm when theoutdoor temperature is relatively low, such as in winter, and plays adustproof role on the wet curtain body. In the present invention, thewet curtain body is provided on a fixing plate, and the fixing plate ishermetically embedded on the sidewall of the henhouse, so in summer,when the wet curtain works normally, the henhouse can be normallyventilated and cooled. When winter comes, the henhouse can be thermallyinsulated according to the actual outdoor temperature. By pulling downthe thermal insulation curtains on both sides of the wet curtain body,it is possible to avoid the outdoor cold air from entering the henhouse,so as to achieve an effect of heat preservation.
